lTo 'au whom a magi-emma.

Be it known-that we,`C

have invented new and useful Im "rovements in Stump-Fullers, ofwhich .tllefo owing is a@ specification.

Our invention relates to; stump l of 14 and an extractor shaft 15. A punon 16 1s and its .primary object is the rovision a device lof this character which shall'be simple, durable and efficient, vwhich shall comprise com aratively few parts, and which sha1 capa le of bein manufactured and sold-at a com aratively ow cost.

With the a ve and other objects vin view,

Vthe invention consists in the'construction,

combination and arrangement of arts here-l inafter fully described and claime and illustrat'ed in the accompanying drawings, where- Figure 1 is a view in trent elevation of a stump puller constructed in accordance'with our invention. 2l is a sectional view thereof taken on a plane extending centrally and verticall therethrough. Fig. 3 is. a view in side e evation of the means b which the shaft is held against backwar movement. Fig. 4 is a perspective view ofthe chain pulley. Fig. 5 is a sectional view on' the line' 5-7-5 of Fig. 2, and Fig. 6 is a view 1n elevation of the lever by means of which the power wheel canbe rotated to 'rewind the operating cable.A

Referr' to the draw' by reference numerals, 1 esignates thenrame of our -improved stump puller. The frame comprises a circular series of standards" 2 which are inclined u on each other. The u per lends of the stan ards 2 are secured toget er by means of a plurality :of bolts 3, and saidends are 1nclosed by means of a' metallic 'cap 4 which adds strength and lstabil-ity to the rame and which rotectsthe upper ends of' the standards 2 rom the elements. The frame is sup ported bv means of runners 5 and 6 which are preferably constructed of wood and which are prevented .from splitting by means of bolts 7 passing transversely therethrough.

The runner 6 'is pivotally secured to one of the standards `2 by means ofa member 8 and is'provided with a clevis 9, said clevis per.

- 'reactions between the runners 5 and 6 and the standards 2 are s uch that they will readilyY assume proper relative ositipons during the moving oft e machine om one place to another. l l l Y I! Su erposed pairs 'of bars 12 are secured in para el alinement to the standards 2. Bearn 13 are secured'to the up er surfaces of the bars 12 for the reception olla power shaft convex surfaces in opposition and. relativelyl spaced. The hub 20 1s secured between and to the spokes l21 by means ofbolts 22 which pass through the spokes-and the hub. The power Wheel also comprises. braces 23 which are secured at their ends to the spokes 21, and annular members 24.V which are secured to the periphery 19 to provide the wheel with a cable receiving groove 25. The hub is providedwith an opening 26 to receive one end of the power shaft 14 which projects beyond the frame, and is provided with one member 27 of a clutch, the other member 28 of the clutch bein fixed on the power shaft. The

29'wh1ch-,isinterposed etween wheel is revolved in one direction, the shaft will be rotated, andi that when the power Wheel is revolved in the reverse direction, the shaftwill not be rotated.

It will be seen that one phase of the rotation of the power wheel is operative, while Athe other phase thereof is inoperative. The power 'wheel is adated to be lrevolved through the medium o an operatin cable 31 -Which is secured at vone end to t e power wheel: and `wound one or more times about the. same, the wound len ths of operatingg4 cable being dis osed initie groove of the awelwheel.-` he operating cable leaves thepower Wheel preferably at a' point below .fthe center `thereo and passes through a pul- .hley 32 swiveled upon one of the standards 2 of the frame. A chain pulley 33 is fixed A#the chain is. assed over the ulle in a direcv.means of a wheel 38, which is loosely mount- *isfdriven at a speed much less than the speed upon the extractor shaft y15 and has its pe riphery formed to provide recesses 34, said recesses being designed to -receive one or; more links of a chain 35 which passes about the pulley. @ne end of the chain is rovided with a ring 36 and the other end t ereof'isV provided with a hook 37. The links of the chain 35 whichfengage in the recesses 34 of the pulley are neld in such recesses by ed upon the oower shaft 14 for contact with the chain pulley, said wheel being provided in its periphery with an annular groove 39JK adapted to receive those portions of the links whichproject above the pulley. The wheel issecured applied .position by collars 40 whichy are mounted on the power shaft 14 and which are in turn secured in applied position by fmeans of setscrews 41.' he connectionl between the chain 35 and pulley 33 is suchv that whenthf' extractor shaft 15 is rotated,

tion to elevate or lower one end thereof.

in practice, a chain, not-shown, is suitably passed about the stump to be pulled, and such chain isc'onnected to the ring 36 .of the chain 35. After the stump has been secured to 'thchain 35 power is applied to thecperating cable 31. The application of power to the cable revolves the power wheel m a direction to operate the power shaft 14. The rotation of the power shaft 14 is trans-- ferred to the. extractor shaft 15 through the medium of the pinions 16 and 17. `As'they pinion 17 is larger than the pinionw 16, it should be apparent that the extractor shaft of. the shaft 14. The vrotation .of the shaft 15 elevates the stump, said shaft is held against accidental back ard rotation by, means of a dog V42' weich is pivotally mounted upon one ofthe' bearings 13 for engagement with a ratchet wheel keyed upon the power shaft 14. `rThe bearing 13 is formed to provide a bearing 4? for the reception of the journal 44 fof the dog 42. The dog 42 is'provided with a crank arm 45, the gravity of which yieldingly holdsthe dog in position for successive en agement with the teeth of the ratchet whee 43. The dog 42 may be thrown out of engagement with the ratchet wheel'43 to permit the extractor shaft 15 to have backward movement by means of a pull cord 46 which is secured at one' end to the crank. arm 45. After the stump has been extracted from the ground,

the machine is moved to the point where it is desired to deposit the stump, and the dog 42 thrown out of engagement with the ratchet wheel, whereupon the weight of the stump Ywill cause it' to gravitate to the rouridi The movement of the stump can e controlledby passing` a hitch iii the operating cable about the snubber Slii securedto ere-.rei

one phase of therotation of thepower wheel is operative, said wheel may be independently rotated to wind the operating cable about the same, and said wheel is adapted to loeV rotated for this purpose through the medium of 'a bar 47 which is provided at one end with a loo 48 adapted to receive a crank pin 49 secured to one of the spokes 21 of lthe power wheel. it should be apparent from-the above description taken in connection with the accompanying drawing, that we provide a machine which is admirably adapted for the purpose for which it is intended, which is simple, durable and eicient, and which may be manufactured and sold at a comparatively low cost. ln view of the manner in which the power wheel is mounted on the power shaft, and in view of the provision of the dog 42, it should be apparent that the operation of the stump puller is of a comparatively less laborious and dangerous nature.

Changes in the form, proportions and minor details of construction may be made within the scope of the claims without departing from the sY irit 'or sacriiicing any of the advantages of the invention.
